Node crashed daily

[Lyong Kim]

Hi, I am recently installed Proxmox VE 6.2 on my old desktops.

One of desktop crashed every day. Actually don't know what time it crashed, but maybe at night time or dawn..?
I mostly toy with the cluster during daytime and till midnight. At that time most things are going well.
Other two node also old but works quietly well.

I'm not sure that it is due to old hardwares or kernel or configurations..
Troublesome desktop's spec:
- CPU: Intel i5-760 Lynfield (4core)
- M/B: MSI MS-7586/P55-CD53
- RAM: 16GB DDR3 Samsung ram







The picture above is the only scene I can spot. Where do I start to solve?

Any suggestions will be welcomed!

have you tried installing Proxmox on Debian buster or you got same error?

RIP: ksm_scan_thread -> could be a hardware memory problem when ksm memory dedup occur.

Maybe try to change memory to see if it's helping

I haven't try to yet. If not a hardware problem, I'll try to install on debian buster later

For now I have limited cpu freq by 2.2Ghz.
I found cpu temerature was too high so that sometimes ethernet link going to down.
I've stressed cpus for getting high temperature to see if it causes problems and found seg faults in syslog.
Maybe memory also be affected by temperature, just a guess.

I'll see what will happen next day by doing limit cpu clocks.
Thanks again!
